It reminds me of the movie Dude, Where's My Car? I haven't watched the whole movie; I just watched a little bit on TV one night. It's about two guys who get stoned and drunk and can't find their car in the morning. That's, I think, the premise of the entire film, but it sounds like it's based on reality.
You also said the emotional brain runs the show, not the thinking brain. Is that when someone experiences psychosis, or is it just from regular use? What happens when the emotional brain takes over? I'm thinking in relation to violence, or crime, or whatever.
